Andrew [12]3 years ago

Answer:

x>-5

Step-by-step explanation:

First, we need to isolate the variable. To start doing this we can add five to both sides. We now have -3x<15. We then have to divde by -3. When working with inequalites you flip the inequality sign when dividing by a negative number. That then leaves us without answer, x>-5.

Vika [28.1K]

Answer:

The distance is 20km

Step-by-step explanation:

Given

y = 20 - 12x

Required

The distance between the\ library\ and\ the school

The function represents the distance y = 20 - 12x

So, when x = 0.

This implies that he has not started moving.

So:

y = 20 - 12 * 0

y = 20 - 0

y = 20

Harry is trying to solve the equation y = 2x2 − x − 6 using the quadratic formula. He has made an error in one of the steps belo
professor190 [17]

Answer:

Step 2

Step-by-step explanation:

The quadratic formula is given by x=-b+-\frac{\sqrt{b^{2}-4ac } }{2a}

Our equation is y = 2x²-x-6

So here our a = 2, b = -1, and c = -6

We can now plug these numbers into our formula

x= -(-1) +-\frac{\sqrt{(-1)^{2}-4(2)(-6) } }{2(2)} = 1 +-\frac{\sqrt{1+24} }{4} = 1+-\frac{\sqrt{25} }{4}

Step 2 is incorrect because it states that "x equals the negative of negative 1 plus or minus the square root of negative one plus forty-eight all over two times 2."

The correct statement would be "x equals the negative of negative 1 plus or minus the square root of positive one plus forty-eight all over two times 2.", because the square of a negative is positive, resulting in a positive one.

Since this step is incorrect, the steps after are also incorrect, but Harry went wrong at Step 2
